摘要
以地理信息系统(GIS)为平台,结合构造地貌研究,利用矢量地形数据,构建了岷山构造带数字高程模型(DEM),初步对岷山构造带,特别是岷山断裂带构造地貌特征进行了分析。研究表明,将DEM与GIS技术结合,辅以遥感图像解译和详细野外地质调查,能够直观地进行坡度、坡向以及地形起伏度和高程的统计分析等研究,在构造地貌研究中具有良好的应用前景。
In recent years, many researchers have been concerned with the evidence of surface processes in their study of plateau and mountain uplift as well as the evolution of orogens. At the same time, the traditional research is becoming quantified, and the key study puts its emphasis on geomorphology. Geological movements such as uplifting and denudation have led to the formation of present relief. Based on the techno-platform of Geographic Information System (GIS), in combination with the geomorphological study, this paper has constructed the Digital Elevation Model (DEM) of the Minshan Tectonic Belt (MTB) and adjacent regions by applying the data of terrain vectorization. Moreover, the authors have applied this technique to visualizing features of active structures of MTB and Minjiang Fault Zone (MFZ).
